The Michelin Pilot Road 4 come in three options: standard 600cc plus sport touring bikes, Trail misnomer, for adventure touring bikes only used on pavement, and GT heavier grand touring bikes that are often loaded with passenger or/and luggage. They all feature the same tread pattern. The variations come in the 2CT technology of Michelin, dual compound composition of the tires with softer rubber on the sides for increased grip, and firmer rubber down the center for greater mileage. The thin sipes that are placed between the large tread grooves, slice through surface water and go into circular reservoirs positioned along the sipe in order to keep more rubber touching the road. The operating temperature range of the Road 4’s reformulated all-silica compound is from 32 degrees to 122 degrees Fahrenheit. This means that there is added safety along with what Michelin says is 20% longer tread wear life than the previous model.
The GT and the standard hoops have the same identical layouts with cooler-running and harder compound zone at the center of the tire – 20% on the back and 50% at the front, flanked by a softer mixture on the shoulders (40% and 20% respectively. The Trail variant that is designed for on-road use on bikes like Yamaha’s Super Tenere which is an adventure-style motorcycle, get its own arrangement with a softer blend at the rear that is similar to the GT and standard front, but only with a wider center band.
With these tires you will note an important improvement in neutrality and steering lightness. The stability is superb, both while cornering and in a straight line. According to the tread design, the key attribute is the wet weather performance. So, if you usually ride in the rain, the Michelin tires will be the rubber that you must have in those conditions.
The Michelin Pilot Power 4 are more expensive than Road 3s, and some tread squirm during fast paced riding. But they deliver a smooth ride over bumps, responsive steering feel and heavy Siping will make magic on wet roads.
